It's interesting that you mention Chrome’s silliness when I find Firefox’ dev tools to be severely lacking, especially for WebExtensions. Examples include:
- complete inability to run code from the console into the content script context
- content script errors are not shown in the console, you have to open a separate Browser Console
- overall buggy dev tools (I don't remember anymore because I stopped using them a long time ago)
I guess every browser lacks something, it's just that we notice when we compare "my browser" to the next one.
Yeah each one has pros and cons. However if your doing POST and GET requests (Or monitoring network traffic in general) Firefox is much much better than Chrome!
